-of the platform therefrom, and the upper around its edge to engage the arms of the raised weighing-surface G, having an oval I eriphery considerably within the rectanguar area of the platform proper, particularly at the corners of the latter. The surface of the platform slopes awayfrom the base of this weighing-surface toward the rectangular edge of the platform, so that there is no danger of'any one carelessly placing the article to be weighed elsewherethan upon the proper weighing-surface, while it is difficult to designedly do so, particularly without detection, and when placed anywhere upon the weighing-surface G the supporting-frame will be subjected to no tilting strain sullicient to interfere with the accurate weighing of the article. The weighing-surface G is substantially flat, being very slightly concaved in the present instance.

' It is of course not essential that the wei ing-surface G shall be oval in shape, an if the entire platform were square instead of being of oblong rectangular shape the weigh-' ing-surface would naturally be made circular; but it may be square or or other rectangular orirregular shape.

in the resnt instance the platform G and the raised weighing-surface G are stamped from sheet metal, the platform being provided with a narrow depending flange e supporting-frame and prevent displacement surface of the entire platform is covered with an enamel finish.

Having thus fully described my invention, I claim 1. A scale-platform provided with a weighingsurface surrounded by a marginal portion, said portion being so inclined as to constitute a non-weighing surface.

2. A rectangular scale-platform provided with a central raised weighing-surface having a curved periphery and a depressed marginal portion surrounding the same and so inclining away therefrom as to constitute a nonweighing surface; substantially as described.

3. In a scale, the combination, with the scale-beam and the platform-supporting frame mounted attwo points thereon, of a weighing platform su ported upon said frame and provided wit a raised weighingsurface occupying a portion only of the area of said platform Within a surrounding marginal portion thereof so inclined as to constitute a non-weighing surface; substantially as described. u

4. in a scale, the combination, with the scale-beam and a platform-supporting frame mounted at two points thereon, of a weighing-platform supported upon said frame and provided with a raised weighing-surface and a depressed marginal portion inclining outwardly and downwardly from the raised weighing-surface and surrounding the same its inclination being such as to make it constitute a non-weighing surface; substantially as described.

5. In a scale, the combination with the scale-beam and the platform supportin frame mounted at two points thereon and provided with four supporting-arms radiating from its center toward the four corners of the platform, of a rectangular weighing-platform mounted at its four corners upon said arms and provided with a raised weighingsurface having an oval periphery located within the rectangular area of the platform within its points of support upon said frame the portion of said platform surrounding said raised surface being so inclined as to constitute a non-weighing surface; substantially as described.
